1. hardware only solution: in the bios, turn off the onboard video (if it has such option). If disabled there in bios then any OS should only find 1 which is your video card not the onboard.

2. I don't know Mandrake. xorg.conf is the file on Slackware.

/etc/X11/X11r6 . . xorg.conf

something akin to that for where it's located.

If disabling the graphics card in BIOS does not work, edit /etc/X11/xorg.conf or /etc/X11/XF86Config-4 (or XF86Config) and search for "Xinerama" and disable it. That should do the trick. Google with "xinerama" if you run into trouble.

If you don't disable the onboard video in hardware, HardDrake is liable to redetect it at boot time. Depending on the vintage of your mobo you should be able to do this either from CMOS setup or, for older mobos, there will be a jumper.

After that you will probably still need to play with the software or possibly run the hardware wizard in "configure your computer".
